Fig. 12.— Left: Positional offsets in RA and Dec for sources detected by both NVSS and<br />

ATATS. Right: Histogram of offsets ( ∆RA 2 +∆Dec 2 ) for sources detected by both NVSS<br />

and ATATS. <strong>The</strong> majority of the matches fall within a radius corresponding to the ATA<br />

synthesized beam (∼ 75 ′′ ) – those at larger radii are mostly spurious matches of an NVSS<br />

source with an unassociated nearby ATA source, where the true match was not detected by<br />

the ATA.
